Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172432, here are decompositions:

5 + 172427 = 172432
11 + 172421 = 172432
59 + 172373 = 172432
89 + 172343 = 172432
101 + 172331 = 172432
149 + 172283 = 172432
173 + 172259 = 172432
233 + 172199 = 172432

Showing the first eight; more decompositions exist.
